Abstract: A method of safe pressurized mud cap drilling includes determining a set point for a surface backpressure choke manifold, injecting sacrificial fluids into a drillstring disposed in a wellbore, injecting weighted mud into an annulus, and monitoring a surface backpressure. If the surface backpressure rises above the set point, closing one or more chokes of the surface backpressure choke manifold in a stepwise incremental manner to increase an injection rate of weighted mud into the annulus. If the surface backpressure falls below the set point, opening the one or more chokes of the surface backpressure choke manifold in a stepwise incremental manner to decrease the injection rate of weighted mud into the annulus. If the surface backpressure is substantially equal to the set point, maintaining a state of the one or more chokes of the surface backpressure choke manifold to maintain the injection rate of weighted muds into the annulus.

Abstract: ABSTRACT A cassette in a diaper pail for holding soiled diapers is configured to provide an interference if it is installed upside down, to ensure proper operation of the diaper pail.  The cassette dispenses a tube in which soiled diapers are enclosed, the cassette including a receptacle for storing the folded tube, the receptacle defining a central opening and having a top and a bottom, the cassette dispensing the tube from its top. The cassette creates an interference with the holder to prevent proper operation of the diaper pail when the receptacle is loaded in the holder upside down, with the top of the receptacle located down; avoids the interference when the receptacle is loaded in the holder with the top located up. The cassette interferes with the lid assembly to prevent proper operation of the lid assembly when the receptacle is loaded upside down. Date Recue/Date Received 2020-12-14

Abstract: The present invention is in the field of oncolytic viruses. The invention provides new poxviruses which are engineered to be defective for the function encoded by the M2L locus (i.e., m2 function). Such poxviruses lack a functional m2 binding activity to at least one or both of CD80 and CD86 co-stimulatory antigens. Said oncolytic poxviruses are preferably vaccinia virus having a total or partial deletion of the M2L locus. The present invention also relates to cells and compositions comprising such poxviruses and their use for treating proliferative diseases such as cancers and for preventing diseases (vaccination, especially in veterinary field). More precisely, the invention provides an alternative to the existing oncolytic viruses which are largely used in virotherapy. The m2-defective poxviruses are particularly useful for the expression of immunomodulatory polypeptides such as anti-CTLA-4 antibodies with the purposes of stimulating or improve immune response.
